HEIC 轉 BMP轉換工具
A free HEIC to BMP converter for High Efficiency Image Container files. Browser-based pairs here usually run in this tab, with no file upload.
把你的 HEIC 檔案拖曳到這裡
or 瀏覽你的裝置 · 貼上快捷鍵 Ctrl+V
Accepts .heic, .heif, .hif files. You can queue several files; each is processed one after another on your own device.
你的檔案不會離開這台裝置——沒有上傳，也沒有伺服器可以刪除它們。
- 01
新增你的 HEIC 檔案
把檔案拖放到上方的方框，或點擊以瀏覽選取。檔案會直接從磁碟讀取——不會傳送到任何地方。
- 02
檢查設定
BMP is already selected. Open the gear icon on any row if you want to change quality, dimensions or codec before converting.
- 03
下載你的 BMP
按下轉換，等待該列完成即可。若轉換多個檔案，可以將它們一起打包成單一 ZIP 檔下載。
HEIC
High Efficiency Image Container自 iOS 11 起，iPhone 預設拍攝的照片格式——在相同畫質下，檔案大小大約是 JPEG 的一半，並支援景深地圖與即時影像（Live Photos）。Windows 與多數網站至今仍無法開啟它，這也是為什麼轉成 JPG 是需求量最大的圖片轉換。

BMP
Windows BitmapWindows 的未壓縮點陣格式：每個像素都完整儲存，因此讀取簡單，但佔用的磁碟空間也非常龐大。幾乎都值得轉換成同樣無損、但小得多的 PNG。

- HEIC is lossy and BMP is lossless. Re-saving cannot recover details removed by the lossy source. The output is usually larger with similar visible quality, not a repaired original.
- HEIC 支援透明背景，而 BMP 不支援，因此原始檔中的任何透明部分，在轉換過程中都會被壓平為實色背景。
關於 HEIC 轉 BMP 的常見問題
這個 HEIC 轉 BMP 轉換器是免費的嗎？
是的。在這裡把 HEIC 轉換為 BMP 完全免費，不需要帳號、沒有浮水印，也沒有每日次數限制。處理在你自己的裝置上完成，因此沒有需要轉嫁給你的伺服器成本。
我的 HEIC 檔案會被上傳到任何地方嗎？
For browser-based pairs, your file is read locally and converted by Squoosh in this tab. No file payload is uploaded; you may still see analytics and engine downloads in network logs.
HEIC 轉 BMP 有檔案大小限制嗎？
There is no imposed upload cap when it runs in-browser, but each conversion still depends on your device and browser memory. Large videos are the first practical limit, then memory-heavy documents or images.
把 HEIC 轉換為 BMP 會損失品質嗎？
Nothing is intentionally discarded in this step, because BMP is lossless. A HEIC file encoded with lossy settings stays lossy, so missing detail is not recovered.
可以一次把多個 HEIC 檔案轉換為 BMP 嗎？
Yes. Drop in several files and each gets its own row; they are processed one after another on your device. You can download them one by one or as one ZIP.
HEIC 轉 BMP 能在手機、Mac 或 Chromebook 上使用嗎？
Most modern browsers on Windows, macOS, Linux, ChromeOS, Android and iOS work. Very large videos are often more reliable on desktop or a browser with more memory.
Why do some conversions take longer on first run?
The conversion engine has to download first. Small codec bundles are fast, while ffmpeg is commonly 12–30 MB; later conversions of similar type use the cached engine.
I converted a file and the output is blank or unusable. What should I check?
Start over with default settings, then change one option at a time (quality, bitrate, page size, or codec) to isolate what changed behavior. If it keeps failing, retry with a smaller file and confirm the source format matches the pair.
